The Device Control command set contains the IPDS commands that initialise the environment for a logical page. Furthermore, it communicates device controls, manages resources, and handles the acknowledgement protocol.
This command set is mandatory.

Finishing Operations |
This field lists all the optional finishing operations that the printer supports at the moment. Finishing devices which have been turned off or are otherwise not available will not appear in the list. The optional finishing operations are found in section about paper output handling. |
The printer supports the following presentation fidelity control triplets:
Colour fidelity, which concerns colour matching
Finishing fidelity, which handles incompatibilities of finishing and media sizes
Text fidelity, which concerns incompatibilities when printing text
CMR tag fidelity, which concerns incompatibilities in Colour Matching Resources
The fidelity controls offer three alternatives:
Continue without an exception
Continue, but report the exception
Stop and report the exception
Two other fidelity types are supported:
Font fidelity, which concerns incompatibilities in font matching and is handled in the printer driver
Media fidelity, which concerns incompatibilities in media matching and is handled in the printer driver
The Invoke CMR IPDS command establishes an application default CMR at the Homestate level. The default CMR is used when there is no data-object CMR or embedded colour profile. If no CMRs are invoked and activated, the device default profile will be used.
Rendering Intent:
A set of rules which define how to translate one colour space to another. While the rendering intents are primarily designed to control the translation of out-of-gamut colours, they may also have an effect on the in-gamut colours.
Device appearance:
This can be used to force a full colour printer to rip in B/W in stead of colour. The purpose can be saving costs or improving RIP-performance if a document contains only a few pages of colour information.
The RPO command requests that a previously stored IOCA Image or Object Container shall be pre-RIP’d and stored for further use. The pre-RIP’d and cached version of the presentation object may later be included on a page or overlay through the Include Data Object IPDS command.
The RPO function works with the following presentation objects:
IOCA images
TIFF object containers
GIF object containers
JFIF/JPEG object containers
PDF object containers
